※ This video is part of <Extreme Job - Wind Power Generation 1-2> broadcast on September 1, 2010. Jeju has already installed more than 40 wind turbines due to its natural characteristics of high winds, but wind turbines are still being built in various places to meet the demand for electricity. However, for the workers installing the turbines, the wind is the greatest enemy that threatens their lives! We meet the people who create the miracle of wind in a workshop without a roof to block the sunlight, installing a tower 76m above the ground, relying on only one safety device, and installing a nacelle and blades weighing over 70 tons on top. The best place for wind power generation, Jeju Wind Power Plant Jeju Island is called the best place for wind power generation due to its excellent wind resources and good installation conditions. There are currently 44 wind turbines installed here, and construction of wind power generation is still in full swing at the Seongsan Wind Power Plant in Seogwipo City. Six units have already been installed, and four more are currently being installed. The four additional generators will be able to produce enough electricity to power approximately 670 households. The extremely dangerous wind turbine installation work that lifts a weight of at least 40 tons to the height of a 24-story apartment building. Let’s hear the story of the “Wind Men” who fight against nature to gain the power of nature. A head-on confrontation with the wind. The wind turbine pillar, the foundation of wind power, boasting a total length of 76m, the tower is installed in three stages. However, the tower installation work, which is greatly affected by the wind to the point that work is halted when the wind speed exceeds 15m/s, is not easy. Manager Kim Seong-won, who has installed nearly 100 towers, says that there were times when he could only install one tower a month because of the wind. The tower shakes from side to side even when the wind speed exceeds 8m/s, making you feel sick. Will the workers be able to safely install the tower on Jeju Island, the island of wind? Install a tower at 76m high, the height of a 24-story apartment building. The installation of a tower divided into three stages is not easy at all, from tightening over 300 bolts one by one to climbing up and down a vertically connected ladder for 20 minutes several times a day for high-altitude work. That is why the upper-level workers do not come down once they climb the tower to save energy and even have their meals delivered by crane. They have no choice but to endure the nausea caused by the tower shaking in the wind under the hot sun. The upper-level workers are always tense because if they accidentally drop something, it can lead to a major accident for the workers below. Raising the nacelle, the heart of a wind turbine The nacelle, the heart of wind power generation where the generator and booster that enable the wind turbine to move are densely packed. It weighs a whopping 76 tons, making it the heaviest part of the generator, making it a difficult task even among wind power installation work. In particular, if the nacelle is not raised immediately after the tower is installed, the wind inside the tower may circulate, which may lead to the collapse of the tower. Therefore, the nacelle must be raised immediately after the tower is installed. However, it is not easy to raise a 76-ton component into the sky. Although a crane is used, there is a risk that the nacelle may hit the tower due to the wind. The workers attach a 300m rope to the nacelle and pull it with all their might from the ground. At this time, the workers are always at risk of being dragged up by the rope. However, it is not easy to stop the 76-ton nacelle from moving. Can the wind power warriors install the 76-ton heavy object, the nacelle? Blade Express Transport Operation A 39m-long blade transport operation is underway. In order for a vehicle carrying a long blade to make a U-turn, a road of at least four lanes is required. Otherwise, the blade may break if it hits a utility pole or building, and all the work up to this point may be in vain. However, it is not easy to control traffic in broad daylight, not even at night. Will the blades be able to safely travel to the work site? In the midst of a typhoon, the last of the wind power installations, the blades! Once the blades are installed, all three must be installed for balance. However, due to the influence of Typhoon Dianmu, the installation is difficult from the start. After much thought, the installation is pushed forward and fortunately, the first blade is successfully installed. However, the second installation work is in danger of being stopped as the wind direction changes. If the blades are raised like this, they could collide with the crane in the air and collapse. To make matters worse, it rains and the work situation becomes even worse. Will the 7th wind power plant be completed? ✔ Program name: E
